SPEGIHGATIGN forming part of Letters IPatent No. 740,717, dated October 6, 1903.

Application filed February 2. 1303. Serial No. 141,480. (No model-l To all whom it may concern:

Be it known that I, J OSEPH WADSWORTH, a citizen of the United States, residing at Paterson, in the countyof Passaic and State of New Jersey, have invented certain new and useful Improvements in Swivel Looms, of which the following is a specification, reference being had therein to the accompanying drawings. r

My invention relates to swivel-looms; and it consists in a swivelshuttle rail carrying a plurality of racks and pinions and superposed banks of compound swivel; shuttles operated by said racks and pinions, each bank of shuttles independently. operative; in means for operating the various banks of swi vel-shuttles simultaneously, alternately, or at any interval desired; in the peculiar construction and arrangement of the said swivel shuttles and the individual supports therefor; in means for changing the position of the swivel-shuttle rail in either direction at alternate inter: vals or intermittently in either direction, and

in various combinations of the above devices and other known parts of the weaving mechanism. of a swivel-loom, as will be hereinafter more specifically set forth in the claims.

The main object of my invention is to pro vide in a swivel-loou1 a mechanism adapted to weave figures comprising various colors atany predetermined position in the fabric being woven or to weave figures some of'one color and some of another color, if so desired, and at any predetermined point without stopping the .loom, the whole mechanism to be automatic in its operation and to be controlled by the jacquard.

, In the drawings similar letters of reference indicate, like parts throughout the various figures of the drawings. A

Figure 1 shows my compound swivel-shuttle rail, partly front and partly back view. Fig. 2 shows partly atop and zpartly a bottom view of my rail. Fig. 3 is a section through my rail on the lines a: a; in Fig. 1. Fig. 4 is an end view of my .rail. Fig. 5.':is.a front viencof theback parte of the bottom come pound swivel-shuttle. Fig. 6 is a plan view loom embodying my invention. Fig. 9 is a plan view, of Fig. 8. Fig. 10 is a left-side elevation of Figs. 8 and 9. Fig. 11 is a plan view of my swivel-shuttle rail on line '5! in Fig. 8. shuttle rail on line 2 in Fig. 8. Fig. 13 is a detail perspective view showing the construction of operative connection of swivel-shuttlerack-moving device for one set of swivel-shut- Fig. 12 is a plan view of my swiveltles on. one side of loom. The same device is An arm A secured to the swivel-shuttle rail, connects it with rod L, which is preferably square and has the rounded portion, as

indicated by the reference-letter Z, at the end of which is secured the downwardly-extending arm ll, having a sleeve Z, that may be secured at the point desired on the round portion Z of the rod L.

The arm Z passes through an opening a in the outer end of the arm A The swivel-shuttle rail carries the sliding racks B and B, the former in part A, the lat= ter in part A, and studs 5 and 19, secured to said racks, extend upwardly through longitudinal vertical slots at and a, in which slots said studs are reciprocated to operate said I I racks. The swivel-shuttle rail is hung on studs a", secured to the plate a which is in turn connected to the mechanism for raising and lowering the rail, and said studs (1 project through the longitudinal horizontal slots a which permit the whole swivel-shuttle rail to be moved laterally, sliding on said studs a to change field of-operations of the top swivel-shuttles E, which is operated by the rackB through the pinions c, and of the lower swivel-shuttles E", operated by the rack 13 through the pinions C.

TheL-shaped supports D and D" of the upperand lower shuttles, the blocks C and C,

ICC

and the pinious c and c" are supported on and I f of the loom-frame F.

through which the securing-screw a is passed.

The rod L is mounted to slide in the brackets Z and Z which are secured to the top rail To the rod L is secured the rack 1 The rod L and the swivelshuttle rail A A, to which it is operatively connected, are caused to move either to the right or to the left by the shifting device K a device fully described in former applications filed by me and which are now pending in the United States Patent Oflice.

The device K comprises a ratchet-wheel and l a pinion k, secured to a stud, levers loosely I mounted on and depending one on .eachside i of said stud,each leverhavingapaWiad-apted to engage said ratchet-wheel and turn it and the pinion inone direction and the other pawl to turn it in the opposite direction, stops to limit the movement of said levers, and means throwing :the respective pawls into or .out .of engagement with the said ratchet. The levers f are operated from the jacquard through the I connecting-cords k, and as the jacquard may lift either lever once or oftener,-s1-iccessively and at intervals, and the intermediate pinion k meshing with both the pinion k and the j rack Z the swivel -.-shuttle rail A A can bef shifted frequently in one .direction at intervals, as desired, to permit theswivel-shuttles to weave figures where required in the fabric being woven.

shafts G G are permittedto slide on the right and left of the loom, respectively.

B and B.

studs 9 Pivoted to said studs g are brackets g pivotally secured at g .to shafts G G 3 below the collars 9 the levers g". Pitmen g and 9 connect,

respectively, levers g with brackets g and 1 (See Figs. 8 and 13 .of'

' could not be disposed :of.

Knuckle-joints 2' and 2' join the levers with the connecting-rod i and said connectthe swivel and allowing it to operate. On the lower ends of the shafts G G are ing-rods i and i are suitably attached to the two vibrators i and '5 of a head-motion, which are operated from the jacquard, as shown in Fig. 14.

The levers 19 are an element in the picking-stick-operating mechanism, and in this case it is not deemed necessary to go into details concerning that.

The rod i is pivotally connected with the lever i by the pin 11 and the rod 2' with lever 2' by the pin 1'.

The vibratorsi and t are operated by a jack M, of the usual or any well-known construction, to which they are operatively con nected by the cords 2' and by levers m and m fulcrumed in a bracket m which may be secured to .or near the jacquard. Said levers m and m are 'held normally ina horizontal position the-springs m the springends .of the levers being connected by the cords m to the jack M,and theopposite ends of the levers are connected to the jacquard by the cords m.

The construction shown anddescribed accomplishes five thingsviz., the weaving automatically of the figures in the fabric where desired; the changing and mixing automaticailly of colors in the -figures without interfering with .or stopping the operation of the loom; the shifting of the swivel-shuttle rail carryinga plurality vorseriesof independently- .operative sets of swivel-shuttles containing I E ating said swivel-shuttles by the upward Brackets a are secured to swivel-shuttlef rail and have arms a secured to 191.23.083.93,

movement of the jacquard mechanism, and obviates the necessity for using acomplex head-motion having chains, &c.

The ordinary way .of operating a swivel- I 2 loom is by having one ground-card between Lever-arms g and g .are suitably mounted on the shafts G and G and are pivotallyconnected by pins 9 with the pitme-n li and 6 f the other ends of said pitmen being pivotal-lysecured to the studs 1) and 'bof the racks each sw vel-pick, and the reason for this arose from the fact that the swivel mechanism on a swivel-loom lies dormant until it is called. This calling takes place in the following manner: As the figure approaches which it is intended to swivel the last ground-card pre- On the picking-stick holders fare secured f yious to the swivel is .cut in such a manner thatcertain hooks are raised up in the jacquard-machine, releasing the mechanism of This ope-ration can be continued indefinitely, but always with a ground-card intervening between the swivel-picks, and this-ground-card was apparently hitherto a necessity which By my invention, however, I dispense with the intervening ground-card between the swivel-picks.

The advantage of this inventioncomes in when it is desiredto make a two-colored swivel e-ifect without any intervening ground-pick. Given .the double-tier swivel-batten and in the regular way of swiveling, we have first one tier, then a ground or blank card, and then the second tier. By means of my levers and springs or other equivalents this invention I ward motion toone revolution of the jacquardmachine by means of my levers and springs. As the machine rises one of the swivel tiers commences to work, and as the jacquard-machine comes down the springs work the jacks,

' so that the second tier of the swivelbatten is operated without any intervening blank card, and this could not be accomplished except by means of my levers and springs or other equivalent means capable of performing the same function. The rising jacquard mechanism, as is readily perceived, can perform the function of pulling up; but it cannot push down nor pull up when it is going down; but with my invention I secure a direct upward pull when the jacquard mechanism is rising and indirectly a rising pull when the jacquard mechanism is descending. The negative motion of the jacquard-machine is virtually converted into a positive motion, the spring acting when the machine is going out of action.

Figs. 15 and 16 will serve to illustrate the advantages of my invention.

In Fig. 15 is shown one ground-pick be-' tween each swivel pick, the colors of the swivel-shuttle thread alternating and having a ground-pick between them. In Fig. 15, s, is a red swivel-pick, g the ground-pick,.and

'8 the blue swivel-pick, g another groundpick, 8 another red swivel-pick, g another ground-pick, 3 another blue swiveLpick, duo.

In Fig. 16 is shown one ground-pick, then two swivel-picks, then a ground-pick, then two more swivel-picks, or between every two ground-picks two swivel-picks of the same or different colors.

In Fig. 16, s and 8, two swivel picks of difierent colors, are shown between every two ground-picks g, 8 being a red swivel-pick, and s a black swivel-pick. V

As is obvious, colors and combinations may bevaried ad Zib'itum.

. The mechanical devices shown in the drawings for indirectly communicating apositive action from the jacquard, or what may be termed the converting of a negative into a positive action although practical and efiect: ive is not only mechanical contrivancapossibly, that might be made to perform the principal function of my inventiomwhich I de-l sire to claim broadly without limiting myself to the specific construction'shown. To. change the patterns on the ordinary swivel-loom entails considerable expense, while with my loom I merely have the expense of cutting my cards. It is obvious that while not necessary on a loom having a single bank of shut-= tles my double-acting jacquard may never-- theless be used to great advantage. The loomshown in the drawings has two banks of swivelshuttles, and either or both simultaneously may be shot through the swivel-shed, according to the pattern, by the operation of the j acquard-machine, and the shuttles may have the silk supplied thereto of the color or colors desired, so that the color or colors desired in the figure are supplied automatically as called for by thepattern.

. It is obvious that any alternation of colors desired may be produced, as either the upper or lower bank of shuttles may be at rest or in operation whenever required. The parts are assembled as indicated in the various figures. The swivel-shuttle rail is operated as above described. i

The upper and lower bank of shuttles are operated as follows: The jacquard through the cordsm tilts the levers m and m and the springs m cause them to return to their horizontal position and cause the jack M by I the cords z to work the vibrators t and 13, which being operatively connected by the shafts 2' and t and levers t', 2', "i and "i with the rods i and 2' cause said rods to reciprocate or slide and turn the shafts Grand G,

and the shafts G and G are connected with and operate the pitmen b and 6 which are rack B, which drives the front or upper shuttlesjE, and the rack B, which drives the back or lower shuttles E.

The peculiar construction and arrangement of my compound swivel-shuttles, as shown, is

'a necessary element of my invention to constitute an efficient and practical swivel-loom, because I may require both the upper 'and lower swivel-shuttlesto carry the swivel-weft ofdifferent colors through the swivel-shed at the same time or not and because it is neces; sary to supply weft when the bobbins in the swivel-shuttles need replenishing. My back or lower shuttle E is therefore a compound swivel-shuttle made in two parts e and, e.

Pins 6 and'e are secured to the part a and are provided with slots 6 The part c is provided with holes a, into which the pins e and 6 enter and are held by the pressure of the.

springs 6 which are secured to the part. 6.

The said springs when pressed by the insertion of the pins e and e enter slots e in the sides of the openings a", locking the parts 2 and 6 together, as shown in Figs. 6 and '7.

attached to the rack-studs b and b to move The part c is L-shaped and'has the rack por-' 7 &
